LA4815VH

Overview

The LA4815VH incorporates a 1-channel power amplifier with a wide operating supply voltage range built into a

surface-mounted package. This IC also has a mute function and requires only a few external components, making it

suitable for low-cost set design.

Applications

Intercoms, door phones, transceivers, radios, toys, home appliances with voice guidance, etc.

Features

• Built-in 1-channel power amplifier

Output power 1 = 1.84W typ. (VCC = 12V, RL = 8Ω, THD = 10%)

Output power 2 = 1.55W typ. (VCC = 9V, RL = 4Ω, THD = 10%)

Output power 3 = 0.36W typ. (VCC = 6V, RL = 8Ω, THD = 10%)

Output power 4 = 0.23W typ. (VCC = 5V, RL = 8Ω, THD = 10%)

• Mute function

• Selectable voltage gain : 2 types
